Correct answer: E — Japanese encephalitis vaccination with rigorous bite avoidance

The best answer is “Japanese encephalitis vaccination with rigorous bite avoidance”. Duration, season, rural night exposure, irrigated agriculture and pigs all materially increase Japanese encephalitis risk. Vaccination is therefore appropriate, but protection is incomplete and must be paired with bite avoidance. Antimalarials and yellow fever vaccine do not protect against JE.
